Mitigating Effects of Interference through Coding and Interleaving

Abstract

Based on the fact that performance of random error correction decoding is insensitive to code symbols erased before its decoding process, a new approach to mitigate the effects of interference is derived. This approach consists of three basic functions: it modifies conventional interleaving, it detects and deletes burst errors, and it corrects random errors. Therefore, this approach minimizes effects of jamming, antenna switching, and nuclear fading. We shall first describe a tactic of integrating coding and interleaving. Then, derivation and application of a special rate-1/4 convolutional code are illustrated. Finally, some preliminary computer simulation results on a rate-1/2 code are utilized to verify the effectiveness of the proposed technique.
